Fluent NHibernate automapping class conventions aren't being applied to entire class hierarchy -

i'm trying automap simple inheritance hierarchy fluent nhibernate, , need have different name each table class (underscores instead of pascal case). seems obvious place use conventions. want use table-per-subclass strategy, combination seems causing me issue: convention applied base class of hierarchy.

here's automapping:

automap     .assemblyof<baserule>()     .includebase<baserule>() // "baserule" abstract class     .conventions.add( defaultcascade.all() )     .conventions.add<oracletablenameconvention>() 

how want classes mapped (class name -> table name):

  abstract class baserule -> base_rule   class numberrule : baserule -> number_rule   class patternstringrule : baserule -> pattern_string_rule 

what i'm getting:

  baserule -> base_rule   numberrule -> numberrule   patternstringrule -> patternstringrule 

as can see, base class being changed. here's existing convention, can see how i'm defining it:

public class oracletablenameconvention : iclassconvention {     public void apply(iclassinstance instance)     {         string fixedname = instance.entitytype.name.tounderscorednaming();         instance.table(fixedname);     } } 

i've looked isubclassconvention interface, , can see no way in there adjust name of table (which makes enough sense, subclasses aren't in own table).

if delete includebase line automapping, names become want, except becomes table-per-concrete-class. want use table-per-subclass, leaving common data in 1 shared base table.

i can add overrides each name, , if have to, i'd rather not.

it seems should supported behavior. how can have naming convention apply each table in hierarchy, without going table-per-concrete-class?

as posted question, figured out.

ijoinedsubclassconvention interface needed implement.

public class oraclesubclassconvention : ijoinedsubclassconvention {     public void apply(ijoinedsubclassinstance instance)     {         string fixedname = instance.entitytype.name.tounderscorednaming();         instance.table(fixedname);     } } 

i found looking had method table(string).
